My Update Manager has had an update in it for weeks now, under Other Updates (LP-PPA-glasen-intel-driver). It is an X.Org Xserver Nouveau Display Driver. When I check the description, it says that it cannot be installed because "This update does not come from a source that supports changelogs".
I'm not sure if this is an update I need to install, but it keeps showing up, and I am having problems with graphics lately--monitor not detected on boot, resolution problems. Would this driver help? And how can I get it to install?
